Change the color of a section in OneNote 2016 for Mac

You can change the color of any section in your notebook — either for aesthetic purposes or to visually categorize your notebook content in OneNote in the same way you might differentiate the sections of a traditional paper notebook.

Change the color of a notebook section

Do the following:

Control-click the tab of the section whose color you want to change, point to Section Color, and then click the color you want.

If you change your mind and you want to apply a different color to the same section, repeat the previous steps with a different selection.
